By any measure, the American Library Association's membership retention level has always been enviable. But the other shoe has dropped in the nation's economic "deep recession," as May figures show. With ALA Publishing Department revenue already in decline, membership dues revenue at $4.3 million is under budget by $127,000 or 2.8%. The number of new and renewing members has declined from 67,827 to 65,437, or -3.52%. On the plus side, ALA continues to see growth in student membership; May numbers were up by 2.3%.
